Defending champion Iga Swiatek beat Zheng Qinwen 6-3, 6-3 on Thursday, avenging her Olympics semi-final loss to the Paris Games gold medallist to reach the last four at Indian Wells. The world number two from Poland will get a chance to avenge another upset loss in a semi-final clash with Mirra Andreeva -- the 17-year-old Russian who stunned her in the quarter-finals at Dubai last month on the way to becoming the youngest-ever WTA 1000 champion.
